This invention relates to metal Weatherstripping and metal frame lining for double hung window construction.

It has been conventional practice to nail or screw metal frame lining or Weatherstripping and parting stops to a window frame being lined or weatherstripped. When it becomes necessary to remove sash in order to replace a Worn or broken sash cord or balance, the frame lining or Weatherstripping and parting stops must be removed. The removal of the frame lining or Weatherstripping and parting stops generally destroys them or bends them to such an extent that they cause binding .of the sash when replaced.

5 Also, the window frame onto which parting stops,

frame lining or Weatherstripping is secured generally warps and causes binding of sash mounted in the Window frame.

When Weatherstripping is installed in remodeling or repair jobs, the window frames are generally bulged, warped or dented which pulls Weatherstripping when nailed thereto out of alignment with respect to the saw out or kerf in the sash which receives the rib .of the weatherstripping with the consequence that the said kerfs must be quite wide and the fit between the sash and the Weatherstrip ribs must be quite free to permit easy sliding of the sash with respect thereto whereupon much of the effectiveness of rib type Weatherstripping is lost. Much time is spent in cutting and fitting frame lining or Weatherstripping in both new and alteration jobs to compensate for irregularities in the window frames to which it is applied. 35 With the foregoing in view, one object of the invention is to provide a metal Weatherstripping or frame lining including a metal parting strip which, as a unit, is entirely self-adjusting to irregularities in a window frame in which it is mounted and to irregularities in the sash hung in the said window frame.

Another object of the invention is to provide the combination of a metal parting strip and metal Weatherstripping which is self-adjusting laterally with respect to the window frame and which will automatically compensate for any irregularities and warping of the face of the window frame or edge of the sash hung therein.

Another object of the invention is to provide a metal Weatherstripping or metal frame lining including a parting strip therefor which may be easily and readily installed, removed for maintenance and reinstalled without damage to the said Weatherstripping or frame lining and parting stop.

iii

Another object of the invention is to provide, in combination, a metal Weatherstripping or frame lining including means for constantly urging the same against the edge of the sash hung in the said window frame, which means provides an air and moisture seal between the back of the said Weatherstripping or frame lining and the window frame to which the same is applied.

Another object of the invention is to provide the combination of a metal Weatherstrip or metal frame lining and a parting stop which is universally self-adjusting with respect to irregularities and warping .of the window frame and sash slidably mounted therein.

Another object of the invention is to provide, in double hung window construction, the combination of a metal parting strip secured to a window frame at the head and sill thereof in such a manner as to allow a limited horizontal universal movement thereof, metal frame lining or Weatherstripping slidably engaged in the base of the said parting stop and retained in kerfs in the blind and trim stops of the window frame, and resilient means also slidably engaged in the base of the said parting stop adapted to urge the said frame lining or Weatherstripping against the edge of the sash hung in the said window frame which simultaneously provides a weatherproof seal between the said lining or Weatherstripping and the window frame which compensates for irregularities in the said window frame and sash whereby to permit warping and swelling of the said window frame and sash without interfering with the sliding of the sash in the lined or weatherstripped window frame.

Other objects of the invention will become apparent by reference to the following detailed description taken in connection with the accompanying drawings, in which:

Fig. 9 is a vertical sectional view taken on the line 9-3 of Fig. 8.

Figs 10 and 11 are enlarged views in perspective, showing in detail the construction disclosed in Figs. 6 and 7 respectively.

Referring now to the drawings wherein like numerals refer to like and corresponding parts throughout the severalviews, the novel weatherstripping. and frame lining units disclosed therein are preferably formed ofsheet galvanized iron, zinc, aluminurmcopper, brass, bronze or other metal which will not rust readily and which will continually present a smooth surface against which wood sash may slide freely. The spring sealing element of the novel Weatherstripping and frame lining units is preferably formed of thin resilient sheet brass or bronze, however, any resilient sheet material may be used therefor.

The novel Weatherstripping unit disclosed in Figs. 2 and 3 is composed of a square or rectangular shaped sheet metal parting strip 20 having a base 2! formed integral therewith in such a manner as to provide a pair of outwardly disposed continuous slots 22 of a width to slidably receive the inner edge of metal Weatherstripping 23 and the inner flange of resilient seals 24 as best shown in Fig. 2, the said slots 22 in the parting strip 20 being sufficiently deep to permit the said weatherstripping .23 and seals 24 to maintain engagement therewithin and at the same time admit of lateral adjustment between the said parting strip 20 and the Weatherstripping 23 and seal 24 engaged in each side thereof.

The rib 25 of the Weatherstripping 23 is so formed as to provide a narrow continuous slot along the back of the said Weatherstripping 23. The resilient seal 24 provided with each piece of Weatherstripping 23 is formed with an outer flange 2% turned at substantially right angles thereto which telescopes into the said slot in the back of the Weatherstripping 23 formed by the continuous rib 25 thereof. The .said resilient seal 24 also has an inner flange 21 bent at a comparatively slight angle opposite to the bend of the .outer flange 26 thereof which causes the continuous corner or sealing edge 260 at the base of the said outer flange 26 to be constantly urged rearward of the plane of the Weatherstripping 23 as shown in Fig. 2 when the said inner flange 21 of a resilient seal 24 and the inner edge of the Weatherstripping 23 is 'telescoped in one of the continuous slots 22 of the parting strip 20. The said angle at which the inner flange 21 of the resilient seal-24 is bent is preferably sufficiently small to avoid causing the outer flange 26 of the said resilient seal 24 from springing out of the rearwardly disposed slot in the Weatherstripping .23 formed by the continuous rib 25 thereof.

Referring now to Figs. 6, 8 and 9, the weatherstripping unit consisting-of a parting strip 20, two .pieces of ribbed Weatherstripping 23 and two resilient seals.24 are assembled together as. indicated in Fig. 2 and positioned against the window frame 28 over an angle retaining clip 29 secured by a screw 30 to the window sill 3| with the upstanding leg thereof located in spaced relationship to the said window frame 28 and disposed centrally between the blind stop 32 and trim stop 33, the said trim stop 33 being previously temporarily removed to admit of hanging the upper sash 34 and lower sash 35 and to permit the outer edges of the Weatherstripping 23 to be positioned in suitable saw cuts or kerfs 3B and 31 provided in the said blind stop 32 and trim stop 33 respectively. The upper sash 34 and lower sash 35 are provided with suitable saw cuts or kerfs 38 and 39 respectively to receive the ribs 25 of the Weatherstripping 23. After the upper sash 34 is properly lined up to slide in a channel formed by the parting strip 20, Weatherstripping 23 and the blind stop 32, and after the lower sash 35 is properly lined up to slide in a channel formed by the parting strip 2!], Weatherstripping 23 and the trimstop 33, an angle retaining clip 40 is secured by a screw 4! to the window head 42 with the depending leg thereof positioned within the end of the parting strip 20 spaced from the sides and base thereof.

It will be particularly noted that, when the sash 3d and 35 are placed against the face of the Weatherstripping 23 with the rib 25 of each piece of Weatherstripping 23 positioned in one of the saw cuts or kerfs 38 and 39 in the said sash 34 and 35 respectively, the said sash 34 and 35 urge the Weatherstripping 23 against the window frame 28 with the continuous corner or sealing edge 260 at the base of the outer flange 26 of each of the resilient seals 24 in contact with the face of the window frame 28, see Fig. 10 in which the face of the window frame 28 is designated by the dot and dash line 283280.

If and when the said window frame 28 and/or the sash 34 and 35 become warped or swelled, or if the window frame 28 and/or the sash 34 and 35 are constructed slightly out of alignment, the novel Weatherstripping unit disclosed in Figs. 2

and 3 compensates for irregularities in the sash 34 and 35 and the window frame 28 and for misalignment thereof in any direction whatsoever. The mounting of the parting stop 20 for a limited horizontal universal movement by means of low- .er and upper retaining clips 23 and 40, the sliding of the Weatherstripping 23 and resilient seal 24 within the slots 22 in the base of the parting stop 23, and the urging of the Weatherstripping 23 and parting stop 20 therebetween outward from the window frame 28 against the edges of the sash '34 and 35 by the spring action of the resilient seals 24 assures a perfectly fitting tightly weatherstripping sash mounting in a window frame employing the novel Weatherstripping unit disclosed herein, the sealing edges 260 of the resilient seals 24 providing a double weather contact or seal between the back of the Weatherstripping 23 and the window frame 28 at all times.

The novel frame lining unit disclosed in Figs. 4 and is composed of a square or rectangular shaped parting strip 20 having a base 2| formed integral therewith in such a manner as to provide a pair of outwardly disposed continuous slots 22 of -a width to slidably receive the inner edge of the metal frame lining strip 43 and the inner flange of resilient seals 44 as best shown in Fig. 4, the said slots 22 in the parting strip 20 being sufli- .cientlydeep to permit the said frame lining 43 and seals 44 to-maintain engagement therewithin and at the same time admit of lateral adjustment between the said parting strip 20 and the frame lining 43 and seal 44 engaged in each side thereof.

The resilient seal 44 provided with each piece of frame lining 43 is formed with an outer flange 4t bent at an angle preferably less than degrees to present a sealing edge 460 which will contact the window frame against which the frame lining unit is mounted as hereinafter described. The said resilient seal 44 has an inner flange 41 bent at an angle less than 45 degrees on the same side of the said resilient seal 44 as the bend of the outer flange 46 thereof. The said bend of the inner flange 47 of the resilient seal 44 causes the continuous sealing edge 463 of the outer flange 46 thereof to be constantly urged rearward of the plane of the frame lining 43 as shown in Fig. 4 when the said inner flange 41 of the resilient seal 44 and the inner edge of the frame lining 43 is telescoped in one of the continuous slots 22 of the parting strip 20.

Referring now to Figs. '7, 8 and 9, the frame lining unit consisting of a parting strip 20, two pieces of frame lining 43 and two resilient seals 44 areassembled together as indicated in Fig. i and positioned against a Window frame 28 over an angle retaining clip 29 secured by a screw 30 to the window sill 3! with the upturned leg thereof located in spaced relationship to the said window frame 28 and disposed centrally between the blind stop 32 and trim stop 33, the said trim stop 33 being previously temporarily removed to admit of hanging the upper sash 34 and lower sash 35 and topermit the outer edges of the frame lining 43 to be positioned in suitable saw cuts or kerfs 3B and 3'6 provided in the said blind stop 32 and trim stop 33 respectively. After the upper sash 34 is properly lined up to slide in a channel formed by the parting stop 20, frame lining 43 and the blind stop 32, and after the lower sash 35 is properly lined up to slide in a channel formed by the parting strip 23, frame lining 43 and the trim stop 33, an angle retaining clip 43 is secured by a screw 4! to the window head 42 with the depending leg thereof positioned within the end of the parting strip 20 spaced from the sides and base thereof.

It will be particularly noted that, when the sash 34 and 35 are placed against the face of the frame lining 43, the said sash 34 and 3'5 urge the frame lining 43 against the window frame 28 with the continuous sealing edge 460 of the outer flange 46 of each of the resilient seals 44 in contact with the face of the window frame 23, see Fig. 11 in which the face of the window frame 23 is designated by the dot and dash line 233-Z8ll.

If and when the said window frame 28 and/or sash 34 and 35 become warped or swelled, or if the window frame 28 and/or the sash 34 and 35 are constructed slightly out of alignment, the novel frame lining disclosed in Figs. 4 and 5 compensates for irregularities in the sash 34 and 35 and window frame 28 and for misalignment thereof in any direction whatsoever. The mounting of the parting stop 20 for a limited horizontal universal movement by means of lower and upper retaining clips 29 and 4d, the sliding of the frame lining 43 and resilient seal 44 within the slots 22 in the base of the parting stop 20, and the urging of the frame lining 43 and the parting stop 20 therebetween outward from the window frame 20 against the edges of the sash 34 and 35 by spring action of the resilient seals 44 assures a perfectly fitting tightly sealed sash mounting in a lined window frame. The urging of the frame lining 43 by the resilient seals 44 against the edges of the sash 34 and 35 provides an effective Weatherstripping, the sealing edges 460 of the said resilient seals providing a double weather contact or seal between the back of the frame lining 43 and the window frame 28 at all times.

Although the installation of the novel weatherstripping units and novel frame lining units have been described to be accomplished in a particular manner or sequence hereinbefore, it is obvious that the installation thereof may be accomplished otherwise to accomplish like and equivalent results.

Although but two embodiments and installations of the invention have been disclosed and described in detail, it is obvious that many changes may be made in the size, shape, details and arrangement of the various elements of the invention without departing from the spirit thereof as defined in the appended claims.
